NAME
       systemd-machine-id-commit.service - Commit transient machine-id to disk
SYNOPSIS
       systemd-machine-id-commit.service
       /usr/lib/systemd/systemd-machine-id-commit
DESCRIPTION
       systemd-machine-id-commit.service is a service responsible for
       committing any transient /etc/machine-id file to a writable file
       system. See machine-id(5) for more information about this file.
       This service is started shortly after local-fs.target if
       /etc/machine-id is an independent mount point (probably a tmpfs one)
       and /etc is writable.  systemd-machine-id-commit will then write
       current machine ID to disk and unmount the transient /etc/machine-id
       file in a race-free manner to ensure that file is always valid for
       other processes.
       Note that the traditional way to initialize the machine ID in
       /etc/machine-id is to use systemd-machine-id-setup by system installer
       tools. You can also use systemd-firstboot(1) to initialize the machine
       ID on mounted (but not booted) system images. The main use case for
       that service is /etc/machine-id being an empty file at boot and initrd
       chaining to systemd giving it a read only file system that will be
       turned read-write later during the boot process.
       There is no consequence if that service fails other than a newer
       machine-id will be generated during next system boot.
